175 Clinical Trials for Various Conditions
The purpose of this study is to evaluate the feasibility of a 6-month family-based community intervention to mitigate cardiovascular disease risk factors in Hispanic families in northern Colorado as measured through biometric screenings, body composition, physical activity, and health knowledge.
The purpose of this study is to identify early cardiovascular disease risk factors in those with "normal-weight obesity" (i.e., normal body, but high body fat percentage) that better track with their long-term cardiovascular disease risk.
This project will assess the effects of consuming different proportions of red meat (RM) and plant-based, protein-rich foods (nuts, seeds, and soy products - NSS) incorporated into a U.S. Healthy Eating Pattern (HEP) on cardiovascular disease risk factors in adults at high risk of developing a heart-related disease.
Our goal is to determine how the addition of sugar-sweetened beverages to the diet affects glucose control, cardiovascular disease risk factors, and pulmonary function in healthy, young adults.
One in three American adults have prediabetes, and up to 70% of adults with prediabetes eventually develop type 2 diabetes. With the high cost of treating diabetes, cost-effective approaches are needed to reduce the incidence of diabetes. One new strategy may be to change when people eat. Studies in rodents suggest that a form of intermittent fasting that limits eating to a short time period each day and involves fasting for the rest of the day (time-restricted eating; TRE) improves blood sugar control and cardiovascular health. Preliminary studies suggest that TRE also improves blood sugar, weight loss, and cardiovascular health in humans. This study will be the first full-scale, controlled feeding trial to determine whether TRE can improve 24-hour blood sugar control, 24-hour blood pressure, and cardiovascular disease risk factors even when food intake is matched to the control group. This clinical trial will also determine whether the benefits of TRE depend on the time of day that people eat. Participants will be assigned to one of three groups: (1) 'Early TRE' (eat between \~8 am-3 pm), (2) 'Mid-day TRE' (eat between \~1 pm - 8 pm), or (3) Control Schedule (\~8 am - 8 pm) for 8 weeks. All food will be provided and matched between groups.
The study aims to compare the effect of a cardiovascular education package intervention on treatment-seeking behavioral outcomes of HCV+ patients. This prospective multicenter trial will compare outcomes between the intervention group (HCV+ patients receiving the enhanced education package) and the control group (HCV+ patients receiving the standard of care, the basic education package). The primary outcome measured will be successful linkage to hepatology for a discussion of HCV treatment options. The secondary outcome measured will be linkage to primary care for chronic disease management.
The objective of this study is to evaluate the effects of different quantities of lean beef (0.5, 2.5, 5.5 oz/day) on lipids, lipoproteins, and vascular health endpoints in the context of a modified Mediterranean dietary pattern that is representative of foods typically consumed in the United States.
The study will determine the feasibility and efficacy of adapting an evidence-based intervention (EBI) to reduce cardiovascular disease (CVD) risk factors in rural African American communities and determine the acceptability of mobile technology in these communities to support behavior change.
This study evaluates the effect of cashew nut consumption on traditional and emerging markers of cardiovascular disease (CVD) risk and determines the usable energy content of a serving of cashew nuts for accurate food labelling.
Purpose : Test the feasibility (acceptability, adherence) of a home-based interval exercise training (IET) and nutrition program, as well as its preliminary effects on resting heart rate, blood pressure, fasting glucose, HDL, cholesterol, weight and percent body fat, among primary care patients who have at least one risk factor for cardiovascular disease (CVD). Participants : 30 patients who receive care from the University of North Carolina (UNC) Family Medicine Center (FMC) and meet the inclusion criteria defined below (i.e. general FMC patients, not diagnosed with severe illness), will be enrolled to test the feasibility of the home-based interval exercise and nutrition program. Procedures (methods): A home-based IET and nutrition program will be piloted in 2 phases. In Phase I, 15 patients will be enrolled into the program, which will take approximately 3 months. At baseline, data will be collected on age, height, weight, resting heart rate, blood pressure, fasting glucose, hemoglobin A1c, fasting lipids, cholesterol, insulin, percent body fat, cardiovascular fitness, and use a series of questionnaires to evaluate mood, sleep, hunger, and quality of life. At closeout, the investigators will measure patients' adherence to each component of the intervention. In Phase II, an additional 15 new patients will be enrolled in either the identical protocol, or a slightly modified intervention (if necessary based upon our results from Phase I). All patients will have the same variables measured at baseline during their study visit at 3, 6 and 12 months after enrollment into the study.
The purpose of this study is to investigate the individual and combined effects of dark chocolate/cocoa and almonds on lipids, lipoproteins, antioxidant defense, lipid peroxidation, phenolic acids, inflammatory status, blood pressure and arterial health. It is hypothesized that dark chocolate/cocoa and/or almonds will favorably affect lipids, lipoproteins, antioxidants, inflammatory status, blood pressure and arterial health compared to a healthy American control diet; however, the effects will be greater when dark chocolate/cocoa and almonds are consumed together versus consumption of each food individually.
The hypothesis of this study is that the natural supplement Capros will decrease LDL levels, platelet aggregation, and serum concentrations of high sensitivity C-reactive protein in humans at risk for cardiovascular disease.
This is a single-site substudy, "Investigation of the Effect of Cenicriviroc (CVC) plus Emtricitabine/Tenofovir (FTC/TDF) on Atherosclerosis Risk Factors", open to all patients enrolled in the primary study, "A Phase 2b Randomized, Double-Blind, Double-Dummy Trial of 100 or 200 mg Once-Daily Doses of Cenicriviroc (CVC, TBR-652) or Once-Daily EFV, Each With Open-Label FTC/TDF, in HIV-1-Infected, Antiretroviral Treatment-Naïve, Adult Patients With Only CCR5-Tropic Virus", in the San Francisco Bay area to evaluate changes in brachial flow mediated dilation in patients in one of three treatment groups: 1. Cenicriviroc (CVC) at 100mg (2 tablets, 50mg each) QD + CVC matching placebo (2 tablets) QD + Efavirenz (EFV) matching placebo (1 capsule) QHS + emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) (1 tablet) QD; 2. CVC at 200mg (4 tablets, 50mg each) QD + EFV matching placebo (1 capsule) QHS + FTC/TDF (1 tablet) QD; 3. CVC matching placebo (4 tablets) QD + EFV 600 mg (1 capsule) QHS + FTC/TDF (1 tablet) QD. The substudy will run for the duration of the primary study. 50 patients of the 150 total enrolled in the primary study will be referred to and enrolled in the cardiovascular substudy. Patients enrolled in the substudy and substudy protocol staff will be blinded to study treatment. Data obtained on this substudy will be analyzed in conjunction with laboratory data for cardiovascular disease risk factors and HIV-1 RNA levels obtained on the primary study. The primary study is a randomized, double-blind, double-dummy, 48-week, comparative study in approximately 150 HIV-1-infected, treatment-naïve patients with CCR5-tropic virus. Patients will be stratified by Screening HIV-1 RNA level (≥100,000 copies/mL versus \<100,000 copies/mL) and randomized 2:2:1 to one of the three treatment groups. Patients will receive all medications from the primary study, and thus the primary study site will be responsible for any adverse outcomes with the drug.
The purpose of this study is to examine the effect of weight loss and exercise on cardiovascular disease risk factors, specifically inflammation as measured by C-Reactive Protein and cardiac structure and function as measured by cardiac MRI, in Class II and III obese women during a 12 week training intervention.
This randomized, open-label, parallel-group, multicenter study will evaluate the rate of cardiovascular events with tocilizumab in comparison to etanercept in participants with rheumatoid arthritis (RA). Participants will be randomized to receive intravenous (IV) 8 milligrams per kilogram (mg/kg) tocilizumab every 4 weeks or subcutaneous 50 milligrams (mg) etanercept weekly, with or without non-biologic disease-modifying anti-rheumatic drug (DMARD).
The investigators hypothesize that cLDL levels are elevated in RA patients and represents an important mechanism for accelerated atherosclerosis leading to excess cardiovascular disease (CVD) in rheumatoid arthritis (RA) patients. The purpose of this study is to improve understanding of the reasons for increased cardiovascular diseases (such as heart attack and stroke) seen in patients with rheumatoid arthritis (RA, an arthritis that causes inflammation and destruction of joints). Specifically, the study plans to determine whether a particular type of change in proteins in LDL cholesterol ("bad cholesterol") known as carbamylation is an important risk factor for cardiovascular diseases in RA patients. The study will utilize a case-control study design. A total of 120 subjects (males and females between the ages of 18 and 80) may be enrolled in order to ensure that 100 subjects (50 RA case subjects and 50 age and sex matched controls) complete the study. Procedures will consist of a single visit for each subject during which a screening evaluation, an enrollment evaluation, and a single blood draw will be performed.
High blood pressure and high cholesterol are both causes of cardiovascular disease (CVD), and it is important for people with these conditions to adhere to their medication regimens. This study will evaluate the effectiveness of a computerized program that provides individualized feedback to participants and their doctors for increasing medication adherence among people at risk of developing CVD.
HIV protease inhibitors (PIs) are a class of antiretroviral drugs used to inhibit viral replication. They do so by interfering with a key step in the replication process. Some HIV PIs have been associated with an increased risk of adverse cardiovascular side effects. Further study is needed, however, to assess the full extent of effect of newer HIV PIs, including atazanavir and lopinavir/ritonavir, on cardiovascular disease risk. This study will compare the effects of atazanavir, lopinavir/ritonavir, and placebo on certain cardiovascular disease risk factors in healthy people without HIV.
Cardiovascular disease (CVD) is a serious health concern for American Indians, but there have been few behaviorally based programs to lessen CVD risk among this population. The purpose of this study is to evaluate whether a Web-based program, in addition to usual medical care, can lower CVD risk factors among American Indians who have type 2 diabetes and a high risk of developing CVD.
The Chinese population is currently the fastest growing ethnic group in New York City (NYC). Research has shown that Chinese immigrants living in NYC have higher rates of cardiovascular disease (CVD) than individuals in China. This study will evaluate the effect that acculturation has on health habits and CVD risk factors in Chinese immigrants living in NYC.
Cardiovascular disease (CVD) affects millions of people in the United States; each year, more people die from CVD than from any other disease. There are many dietary and lifestyle factors that may increase the risk of developing CVD. Preliminary research has shown that the presence of certain trace elements may be associated with the development of CVD. This study will examine toenail clippings and laboratory data to evaluate the link between trace elements and CVD risk factors in young adults.
The objective of this study was to evaluate the efficacy and feasibility of a 12-week behavioral counseling intervention that has been integrated into the primary care setting on psychosocial, behavioral, and health outcomes in a large sample of adults with at least one CVD risk factor. Aim 1: Evaluate the efficacy of a 12-week behavioral counseling intervention on psychosocial outcomes of adults with at least one CVD risk factor. H1: We hypothesize participants will improve their behavioral regulation skills and habit formation skills over 12 weeks. Aim 2: Evaluate the efficacy of a 12-week behavioral counseling intervention on behavioral outcomes (physical activity, diet, and sleep) of adults with at least one CVD risk factor. H2: We hypothesize participants will improve PA (daily steps), diet (total daily kilocalories), and sleep (sleep time, sleep efficiency) over the 12-week intervention. Aim 3: Evaluate the efficacy of a 12-week behavioral counseling intervention on health outcomes (blood pressure, weight, waist circumference, body composition, quality of life) of adults with at least one CVD risk factor. H3: We hypothesize participants will improve blood pressure, weight, waist circumference, body composition, quality of life over the 12-week intervention.
This study addresses two challenges seen among African American (AA) participants during previous weight loss and dietary interventions aimed at reducing cardiovascular disease (CVD) risk: poor weight loss results and high attrition rates. Investigators will target both of these challenges by using a randomized design to compare a plant-based dietary intervention (vegan diet) vs. an omnivorous (omni) diet and by focusing on culturally-tailored food choices for AA adults living in the South. Therefore, the objective of the study is to conduct a culturally-tailored, randomized trial examining how a vegan diet affects CVD risk factors and weight as compared with an omni diet. The study will randomize overweight AA adults (n=130) to follow one of two different diets (vegan or omni) for 24 months. Investigators will accomplish objectives and test hypotheses by following two specific primary aims: Primary Aims: Using a randomized design, determine the impact at 12 months of two different, culturally tailored diets (n=65 omni and n=65 vegan) on changes in: 1. Risk factors for CVD, including LDL cholesterol and blood pressure; and 2. Body weight. Secondary Aim 3. Examine long-term changes in CVD risk factors and body weight at 24 months.
The purpose of this study is to evaluate the effects of cranberry juice on central and peripheral blood pressure, indices of arterial stiffness, lipid and lipoprotein concentrations and size characteristics, and HDL function. The investigators hypothesize that the bioactive compounds in cranberry juice may elicit beneficial effects on blood pressure and arterial health, as well as LDL-C and HDL function.
The ultimate goal of our partnership with local African-American churches is to implement an effective, multi-component intervention to increase awareness of the critical importance of healthy lifestyle in the prevention of cardiovascular disease (CVD). We will utilize the American Heart Association (AHA) prevention strategy, \"Life's Simple 7\" to address the major risk factors for CVD: diet, smoking, physical inactivity, hypertension, diabetes, cholesterol and obesity in order to improve overall cardiovascular health. Our main strategy consists of a community-based participatory research approach that involves focus groups to assess participant knowledge and beliefs about CVD risk factors prior to program initiation. We will also determine participant dietary and exercise practices, knowledge and perceptions related to healthy lifestyle and chronic diseases, demographic/health status information, health care utilization, biometrics (weight, blood pressure, blood tests for glucose and cholesterol, etc.) and attitudes about medical research at baseline, program completion and 6-month follow-up.
The investigators hypothesize that the degree to which older generally healthy but sedentary men and women improve a number of cardiovascular (CV) disease risk factors with 6 months of highly-standardized endurance exercise training will be a function of common genetic variations in candidate genes.
The goal of this clinical trial is to learn if the drug semaglutide changes markers of disease risk as it relates to weight in children ages 12-15 years old who are obese (class 2 or 3). The main questions it aims to answer are: * How do the rate of weight loss, body mass index (BMI), body composition, heart structure and function, and exercise ability interact with one another in the study population at enrollment? * How do risk markers of disease change over the study in the study participants who are given semaglutides to help with weight loss? * Are there differences in the above factors between males and females and are there key factors to help improve the outcomes? Participants will be given semaglutide for this study. During the course of the study, participants will: * have two cardiac MRI scans OR two cardiac echocardiograms (one before starting semaglutide and one around 12 months after taking the drug) * have body composition and fitness levels assessed twice (before semaglutide and around 12 months after taking it) and have urine specific gravity (USG) measured * have extra blood drawn when labs their doctor orders are already being drawn (once at the beginning of the study, once around 6 months after enrollment, and once at the end of the study) * have follow up visits with the study doctor * be asked to take a pregnancy test if they are female and have started menstruation
The aim of this pilot study is to determine the effects of a 12-week indoor rock climbing training program on heart health, mental health, and behavioral health in generally healthy adults aged 18-35 years old who do not exercise. Participants will learn to rock climb using ropes on an indoor rock climbing wall and participate in the training program 2-3 days per week for 60 minutes each session over 12 weeks. Health outcomes will be measured at 4 time points over the course of the study (pre-intervention, 6-weeks/mid-intervention, 12-weeks/post-intervention, and 24-weeks post-intervention).
Unplanned readmissions after hospitalization for acute myocardial infarction (AMI) are among the leading causes of preventable morbidity, mortality, and healthcare costs. Digital health interventions (DHI) could be an effective tool in promoting self-management, adherence to guideline directed therapy, and cardiovascular risk reduction. A DHI developed at Johns Hopkins-the Corrie Health Digital Platform-includes the first cardiology Apple CareKit smartphone application, paired with an Apple Watch and iHealth Bluetooth-enabled blood pressure monitor. Corrie targets: (1) self-management of cardiac medications, (2) self-tracking of vital signs, (3) education about cardiovascular disease through articles and animated videos, and (4) care coordination that includes cardiac rehabilitation and outpatient follow-up appointments. In this prospective study, STEMI or type 1 NSTEMI patients are being enrolled to use the Corrie Health Digital Platform beginning early during participants' hospital stay. Enrollment sites include Johns Hopkins Hospital, Johns Hopkins Bayview Medical Center, Massachusetts General Hospital, and Reading Hospital. The primary objective is to compare time to first readmission within 30 days post-discharge among patients with the Corrie Health Digital Platform to patients in the historical standard of care comparison group.
The purpose of this study is to evaluate the effects of freeze dried strawberry powder on LDL cholesterol, central and peripheral blood pressure, indices of arterial stiffness, and other lipid and lipoprotein concentrations. The investigators hypothesize that the bioactive compounds in freeze dried strawberry powder may elicit beneficial effects on LDL cholesterol, as well as blood pressure and arterial health.
